• The experimental probability of rolling 3 is 16.6% and the theoretical probability is 15%

• The experimental probability of rolling 3 is 15% and the theoretical probability is 16.6%

• The experimental probability of rolling 1 is greater than the theoretical probability

• The experimental probability of rolling 6 is 16.6% and the theoretical probability of rolling 6 is 25%

If the spinner was spun 50 times and landed on 11 fifteen times, which statement is true?

• The experimental probability of landing on 11 is 1/8 while the theoretical probability of landing on 11 is 3/10

• The theoretical probability of landing on 11 is 12.5% while the experimental probability of landing on 11 is 30%

• The experimental probability of landing on 11 is less than the theoretical probability of landing on 11

• The theoretical probability of landing on 11 is equal to the experimental probability of landing on 11

During a festival game, children attempt to wind a prize by drawing a token from a bag. The tokens are labeled Large Prize, Small Prize, or No Prize. After a token is drawn, it is returned to the bag. The table on the left shows the three types of tokens and the number of each token in the bag.

Lia observes the game and keeps track of 20 consecutive draws from the bag. She records her results in the table shown on the right.

Which statements about the game are true? Drag each statement to the True or False category.

Groups:

(a) True

,

(b) False

• Based on the theoretical probability, it is more likely to win a small prize than a large prize.

• The theoretical probability of winning a small prize is 0.10.

• The theoretical probability of winning a large prize is 0.125.

• The observed probability model matches the theoretical probability model.

• From Lia's observed frequencies, the probability of getting no prize is 0.65.

• From Lia's observed frequencies, the probability of winning a large or small prize is 0.7.
